On an updated Mac OS X 10.8.3, both updated Safari and updated Chrome complain about the SSL certificate. In addition, the CLI git command also complains. According to the CA website: http://www.digicert.com/help/, both www.bitbucket.org and bitbucket.org return the error "Your server is not sending the right intermediate certificates." The error text reads:
*Your server is sending outdated intermediate certificates. For optimal performance and security, you should update the intermediate certificates on your server.
To resolve this problem, log in to your account, and re-download the intermediate certificates, then update your intermediate cert file on the server and restart the service.
If you are not sure how to do this, please contact DigiCert support by live chat, email at email@example.com, or phone at 801-701-9600.*
